US ambassador killed amid growing insecurity in Libya

The lack of security in Libya was brought abruptly to the world's attention this week as the US ambassador, Christopher Stevens, was killed in Benghazi. Since Muammar Gaddafi was ousted in August 2011, the country has spiralled out of control with self-appointed militias placing themselves in charge of policing. The new government desperately needs to get proper law and order authorities in place; Gaddafi's $23bn arsenal of weapons has been looted and locals fear for their safety.
